Bellybuttons
"What's that?"
Seth pointed to a nude she'd found in an art book.
"That's a bellybutton," explained Lilith.
"What's that?"
"It's what's leftover of the umbilical chord after birth. All mammals have them."
"But… I don't have one."
"That's because we were made in a lab," interjected Cain. "We are not ordinary mammals."
"Even if we were ordinary humans, we still wouldn't be ordinary mammals," muttered Abel. "Humans are the most selfish, self-destructive creatures in existence."
"But humans have the greatest capacity for good," said Lilith, admonishing.
"What good is that which they don't use?" Abel demanded before stalking away.
A/N: Well... it is entirely possible that, being grown in test tubes, the four of them might not have had bellybuttons. Then again, they may very well have. I don't really know much of how exactly one would, er, grow a human. I mean, I know how in vitro fertilization works, and I assume it would start with something like that, but if they'd make an artificial womb or what, I dunno. This was just a thought I had while at my sister's house for Thanksgiving.
